TSXAEY1600 多轴联动控制技术是数控机床控制的核心技术之一。数控机床各进给轴(包括直线坐标进给轴和回转坐标进给轴)在数控装置控制下按照程序指令同时运动称为多轴联动控制。数控机床一般都具有3轴或3轴以上联动控制功能，多为4轴联动或5轴联动。各个进给坐标轴的运动一般由电动机在伺服驱动器控制下实现，因此，的坐标轴进给伺服装置构成了实现多轴联动控制的物理基础。多轴联动控制就是根据数控加工程序给出运动轨迹(即走刀轨迹)，通过轨迹插补和实时控制，在每个伺服控制周期给出各个联动坐标轴的运动增量，实时控制所有坐标轴的同时运动(simultaneous motion)。

轨迹插补也是数控机床控制的核心技术之一。实现插补运算的装置(或软件模块)称为插补器，现代数控机床普遍采用数字计算机通过软件实现轨迹插补。轨迹插补技术的发展过程如图7所示。从实现的插补功能角度来看，2轴联动的平面点位控制、平面直线和圆弧插补是简单的插补功能；2.5轴联动插补实际上只有2轴联动控制，其第3轴只能实现与另外2轴非联动的控制，这样的联动插补方式可加工3D的曲线和曲面，但效率低、适应性差；3轴联动插补除了实现平面和空间的直线插补、圆弧插补功能外，数控系统还具有螺旋线插补、抛物线插补等功能；5轴联动插补可方便地实现各种复杂曲线和曲面插补的功能，并进一步发展样条插补和先进的速度、加速度、加速度变化率(Jerk)等控制功能，是高速度、、高 动态响应加工的核心技术。笔者认为，未来的数控装置还将发展自由曲面直接插补功能(SDI)，并可望与基于人工智能和数字孪生的走刀轨迹规划相结合，在考虑多轴联动动力学模型以及轨迹误差和速度约束条件下，实现由3D模型驱动的刀轨生成和优控制的多轴联动直接插补。
